Working together, it takes two computers 5 minutes to send out a company's email. If it takes the slower computer 15 minutes to do the job on it's own, how long will it take the faster computer to do the job on it's own?

i believe the answer is c.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
